5. Local Monitoring Unit
1) Setting up the monitoring unit
▪ Power up the monitoring unit and operate like the followings.
・ The LED for Sensor number/temperature/humidity displays 1 to G(16) in
order.
・ All o transmitting LED lights on green and red each just one time.
・ Alarm 1 and alarm 2 sounds for a few times.
▪ After initializing, the LED of monitoring unit is all out and the LED for sensor
number/temperature/humidity displays “_ _ _ _”.
2) Sensor No. LED
▪ Each monitoring unit has its own sensor number.
▪ Sensor number automatically rotates 1,2,3,4,5,6,7,8, 9, A, B, C, D, E, F, G and
displays temperature/humidity for each of them. Each sensor displays at 4
seconds intervals.
3) Temperature LED
▪ Each sensing unit has its own sensor number and displays temperature “℃”.
4) Humidity LED
▪ Each sensing unit has it’s own sensor number and displays humidity “%”
5) Transmitting signal LED
▪ When sensing units normally transmits, LED lights green.
▪ If sensing unit has a temperature lower than the lower limit or more than the
upper limit, the LED of monitoring unit blinks on red at 0.5 seconds intervals.
▪ When monitoring unit can’t receive any results from sensing unit over presented
interval, LED turns on red.
▪ 2 hours after alarm occurred and if it is not all clear, LED of alarm relevant to
sensing unit is out.
▪ The LED of not existed sensing unit is not light on.
6) Sensor No. rotate button
▪ If you want to check next sensor No., press this button.
7) Mute
▪ If alarm occurred, you can press the button to mute the sound.
▪ After 10 minutes of mute, if it is still in warning condition, alarm will be occurred
again.
8) Alarm off
▪ Alarm is let you know in abnormal temperature and situation of sensing unit.
You can slide this switch to right to do not sound alarm at all.
▪ Factory default (and for general use) the switch is alarm-on.
▪ If the button sets up alarm off, it has no sound but LED displays still in warning.
9) Buzzer/Alarm operation
▪ If sensing unit has a temperature lower than the lower limit or more than the
upper limit, Alarm1 will be occurred every 0.3 seconds.
▪ If transmitting is abnormal, alarm2 will be occurred every 2 seconds.
▪ Alarm will be occurred until press the mute button or slide the alarm-off switch.

6. Setting up the GreenOK
1) Antenna
▪ Before setting it up, the antennas of sensing unit and monitoring unit move to
adjust the vertical position.
2) Sensing unit and monitoring unit can be on the table or on the wall using a loop.
▪ For desk or table: stand up the body on a flat part.
▪ For wall: Hang this product using by loop on the wall.
3) Setting up the sensing unit
▪ Restricting the air flow can cause it to take an accurate measurement.
▪ Avoid leaving the wire less thermo-hygro monitor in direct sunlight or shock,
gale.
